What is happening I have Tremors over my entire body?

Diagnosed with microscopic Polyangitis in April 2016. Slight tremor began in my head and neck about 2 weeks after hospitalized. Today, it has been non stop, head to toe. It's so exaggerated I have to hold my hand to drink water. It is maddening. My head and neck are sore to move or touch. Saw rheumatologist Wednesday this week, he would not touch it. Sending me to neurologist 9-19... I can't wait a month but I don't know what to do. Can anyone offer any advice? Thanks for reading.

Going with the microscopic Polyangitis is Lupus, SLE, Sclerederma, Raynauds. These tremors are maddening and can certainly get one prepared for the eternal nap! I can't make it another month and my Rheumy just refused to give me anything to slow this down..I just came off dialysis (4 months) last Sat....with no problems. I get one issue fixed and three more find me. Getting very tired and discouraged. I pray someone out there can help...thanks!
